  • 무선 통신 기술 발전을 통하여 철도환경에서 안정적인 무선 접속과 다양한 통신 기능 제공이 가능함에 따라 철도서비스 고도화의 기반이 마련되었다. 특히, 최근의 무선 통신 기술은 향상된 철도 승객서비스뿐만 아니라 효율적이고 안전한 철도 운영을 가능하게 한다. LTE 기반의 무선통신 기술은 다양한 경제적 혜택과 높은 통신 성능을 철도 산업에 제공 가능함에 따라 세계적으로 차세대 철도 통신 시스템의 후보 기술로 각광받고 있다. 그러나 철도 통신은 열차의 안전한 운행을 위하여 매우 엄격한 철도 통신만의 요구 사항도 존재한다. 본 논문에서는 미래의 철도 통신이 반드시 갖추어야 할 요구사항과 기능을 설명한다. 또한 LTE 무선 통신 기술이 철도 분야의 통신 요구사항을 만족하는지에 대해서도 서술한다. 마지막으로 최근 진행되고 있는 차세대 철도 통합무선망의 국내외 표준화 동향과 구축일정에 대하여 설명한다.

  • Recently many disadvantageous problems have been found during the process of domestic LRT(Light Rail Transit) projects and that can influence negative effects on the development of domestic railway. Since many projects have been progressed while having few original technologies, it is no exaggeration to say that they are being built unreasonable railway which lacks economic feasibility. The on-going LRT projects which are being carried out by the central or local government have a tendency to favor the systems and rolling stocks that have been approved by other countries through years of experience, therefore it can be said that we are having few chances to develop original technologies. In this study, we would like to promote railway development and jump up to the level of advanced railway standards through developing our unique and independent future LRT technology.

  • The public, mass transportation, monopoly, speediness and the long distance transportation of railway have realized by representative advantage from former days. But realization for railway that is declining by industry on the decline by the 1970s since the 1st World War has been changing recently newly. Development of a technology and fast change of industry environment exerted big effect about traffic. And IT and wave in 21C that is spoken for to environment changed together paradigm for railway. Now, is forecasted that period 'Renaissance of railway' may set on the near future because road embankment is getting into the spotlight again by the future alternative among transportation worldwide. In this paper, characteristic of railway to move altered how, and paradigms of been rising railway quality wish to examine what it is newly.

  • This primary study has some bounds md limits owing to the descriptive reviews but not detailed analyses. However, 1 tried to do the comparative analyses and case studies about location and size of rail station for future efficient use of spatial structure. Therefore, I reviewed the location of railway station and some design standards of railway station facilities by type (high speed rail, conventional rail and urban rail), and also, suggested future direction for rail station as the core of city development relating with urban structures and human settlement system reformation.

  • Vehicle braking in non-electrified rail systems wastes energy. Advanced flywheel technology presents a way to capture and reuse this braking energy to improve vehicle efficiency and so reduce the operating costs and environmental impact of diesel trains. This paper highlights the suitability of flywheels for rail vehicle applications, and proposes a novel mechanical transmission system to apply regenerative braking using a flywheel energy storage device. A computational model is used to illustrate the operation and potential benefits of the energy storage system.

  • The railway project is an essential green transportation tool that is considered suitable for the domestic and foreign policy direction of carbon neutrality, but there are some limitations, such as damaging important carbon absorption sources during construction. This study analyzed the environmental impact assessment related to carbon absorption sources of greenhouse gas evaluation items conducted during the railway project, and limitations and implications were derived. The analysis of environmental impact assessment guidelines related to railway projects and carbon absorption sources dealt with prediction and reduction methods related to carbon absorption sources, but guidelines, including environmentally friendly railway construction guidelines, lacked descriptions. Since the greenhouse gas environmental impact assessment, 83 railway project environmental impact assessments have been reviewed, but in some cases, carbon absorption-related predictions have not been implemented, or carbon absorption-related reduction measures have been insufficient. In addition, there were cases where there was a limit to calculating emissions and reduction or where the reduction value was insignificant compared to emissions. In order to supplement the environmental impact assessment in the field of carbon absorption sources related to railway construction projects, alternatives such as quantitative emission and low reduction calculation, review of the no net loss system using the total environmental resource system, and linkage with climate change impact assessment are needed.

  • The article expounds that the speed competition is the motive force of each transportation means. It also analyzes the current condition of the speed of Chinese railways. The developing strategy for Chinese railway is to raise the speed of the existing lines as a primary step and to construct the high-speed railway in selected sections concurrently, which proved that constructing high-speed railway in Beijing-Shanghai area is the best choice.

  • If GNSS-based location information, expected to become the mainstream of the future technology, is applied to the future transportation, it will be of benefit to as follows; cost reducing effects on operating expanse and constructing expense due to decrease of ground unit installation, development of new technologies for train, or vehicle control system and becoming a front runner in the market. Therefore, this paper provides the minimum requirements for GNSS based system thru the studies on the applicability of GNSS based system to railway system, distinctions of the new technology between the existing technologies, and location accuracy.

  • 본 논문은 철도의 발전과 함께 철도문화유산에 대한 중요성이 점차 인식됨에 따라 현재 우리나라의 철도문화유산 지정제도 및 철도문화재현황을 검토한 후 향후 개선방안을 제시하고 함에 그 목적이 있다. 이를 위해 철도문화유산의 보존과 관리체계가 잘 되어 있는 일본의 사례 분석을 통하여 향후 우리나라에서의 철도유산을 어떻게 보존하여야 할 것인가에 대한 방향성을 정립하고자 하였다. 일본은 과거 철도가 국가 소유였을 때와 민영화 이후에는 많은 다양한 변화가 있었고, 철도를 직접 운영하고 건설하는 기관에서의 철도 문화를 체계적으로 관리하고 있어 우리에게 많은 시사점을 주고 있다. 이에 본 연구에서는 한국과 일본 간의 철도문화유산제도를 비교해 보고 그 시사점을 도출하여 향후 우리나라 철도문화유산의 보존을 위한 보다 체계적이고 합리적인 방안을 제안하고자 하였다.
